Police say a nearly weeklong search for a Western District shooting suspect ended when officers arrested 31-year-old Michael Garrison in Windsor Mill on June 12. Garrison had been wanted in connection with a June 7 shooting in the 500 block of North Monroe Street that left a 53-year-old man wounded and sent to an area hospital.

According to Baltimore Police, Western District patrol officers were first sent to the scene on a ShotSpotter alert that same day, where they found the injured man. The department advisory states that detectives later identified Garrison as a suspect wanted in the case and took him into custody on June 12 in Windsor Mill. He is now charged with attempted first-degree murder along with multiple handgun-related counts.
How ShotSpotter helped officers respond
Baltimore has relied on ShotSpotter gun-detection sensors since 2018 to pinpoint possible gunfire and speed patrol response in neighborhoods where shootings might otherwise go unreported. Local coverage at the time described how acoustic alerts are reviewed by analysts, then pushed out to officers so they can get to scenes faster. CBS Baltimore reported on the system's early rollout and funding, which helped put the network in place before incidents like this one.
Western District detectives are asking anyone with information about the June 7 shooting to call 410-396-2477 or Metro Crime Stoppers at 1-866-7LOCKUP, according to the advisory. Baltimore Police also reminded residents to use 911 for emergencies and noted that tips can be submitted anonymously through Metro Crime Stoppers.
Where this arrest fits into local investigations
The case is one of several Western District investigations this year where detectives have followed up on ShotSpotter alerts and witness tips to make arrests. Neighborhood reporting on a March case showed that officers sometimes announce arrests on social media before formal court filings hit the docket. Coverage of a March arrest that capped months of follow-up work on a September shooting highlighted that pattern.
Charges and legal exposure
Garrison is charged with attempted first-degree murder and multiple handgun violations, offenses that carry steep penalties if he is convicted. Under Maryland law, an attempt to commit first-degree murder is a felony punishable by imprisonment not exceeding life, and the statute covering the use of a firearm in the commission of a felony sets a mandatory minimum sentence of five years. Those provisions are detailed in documents from the Maryland General Assembly and in Maryland Code §4-204.
Baltimore Police did not immediately release additional information about a possible motive or whether any criminal charges have been formally filed in court. The state's attorney's office had not posted a charging document as of publication. Records have been requested, and this story will be updated if they become available.
